A retail store ordered some sofas and chairs from a manufacturer. The number of chairs ordered was
four more than the number of sofas. The
received a partial shipment consisting of half of the
sofas and one-third of the chairs that were ordered.
If the total number of pieces was the same as the
number of sofas originally ordered, how many sofas
did the store receive?

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
